/**
 * @assertion Isolate current
 *   Return an Isolate object representing the current isolate.
 *   The current isolate for code using current is the isolate running the code.
 *   The isolate object provides the capabilities required to inspect, pause
 * or kill the isolate, and allows granting these capabilities to others.
 *   It is possible to pause the current isolate, but doing so without first
 * passing the ability to resume it again to another isolate, is a sure way
 * to hang your program.
 *
 * @description Check that current property is not null for new isolate
